Hello Esteemed Cloud Climbers :) I may be acquiring a self-supporting ~85ft (after assembled) galvanized steel monopole. Its diameter is graduated from a ~5ft base to 2ft on top (3 sections). I'm pla
Be aware that you'll also have to figure out a way to attach a rotator and mast to the pole for your beams. Most likely you'll have to fabricate everything yourself. Perhaps a giant ring rotator coul

Yep, planning on a small crane. Not sure this type of flange is ideal for a buried pier footing. I've not found specific details on those beyond conceptual, though. Also planning to fabricate a cross
these sound as typical of Hwy lighting tower as well, but this is a dream tower for the right person, it wont be cheep to fab up a fixed schism to hold a rotor and mast but at the same time not prohi
I would plan on mounting the rotator and mast outside of the pole, rather than inside. I'd install a couple of "ring collars" - off the shelf weldments used in the cell business - one at the pole top
Rethinking what Steve has just posted, yah you bet some outside rings and mast/rotor centering is solved big time in a very positive way solid way. I'm all in now mm I'd install a couple of "ring c

Good thoughts, I had considered a similar approach, and that may really be the way to go. Any thoughts on foundation design? Or cost thoughts on a reasonable PE if that's needed? I'm committed to giv
BTW on one of the other collar faces you could clamp a heavy duty gin pole to make life easy. -Steve K8LX I would plan on mounting the rotator and mast outside of the pole, rather than inside. I'd in
The three common pole foundations are deep caisson, pad & pier, and big block, in that order. To get it engineered you would need a geo survey ($1500-$2500), which the manufacturer would use to *sugg

Thanks, that's good info. Are there rules of thumb on coming up with the overkill mop design? I can make some assumptions based on height and surface, but I've not seen a standard formula or calculat

How difficult are monopoles to climb and work on antennas while on them? Every time that I see a crew on them they are hanging from a crane. John KK9A I would plan on mounting the rotator and mast ou
Good idea. I might use a piece of R45. I used to occasionally see an R25 pointy top section attached to the top of wooden utility poles. Same idea. -Steve K8LX Along the save lines as what Steve said
They typically have climbing pegs and a safety climb cable. For installing top mounted collars and platforms a crane is normally used. Once the platform is there, other work can be accomplished with

Very interesting post. I worked for a two-way shop for 27 years. When we were in search of a local tower guy for subcontracting I found a tree climber. The tree guy said that he had climbed dozens of
